After a violation of undisclosed team rules, Northwestern senior running back Venric Mark has been suspended for the first two games of the Wildcats’ season for an undisclosed violation of team policy, the university announced Friday.

“I made a mistake and am prepared to deal with the consequences of that,” Mark said in a statement. “There’s no one (who) holds me to a higher standard than the one I hold myself to, so nobody is more disappointed than I am.”

Mark is coming off an injury-plagued 2013 season in which he saw action in just three games. During his sophomore year, Mark rushed for 1,366 yards and notched 13 touchdowns for the Wildcats.

Northwestern opens the season Aug. 30 at Ryan Field against California. The Wildcats’ second game is at home against Northern Illinois on Sept. 6. Mark would be eligible to play in the third game at home against Western Illinois on Sept. 20.
